Obtaining assent from potential research participants is an important component of research for reasons related to ethics compliance, self-determination, and choice. However, unique issues arise when working with populations who cannot assent through traditional means, such as individuals with Autism Spectrum Disorder (ASD) and related developmental disabilities (DD). The purpose of this paper is to review and discuss assent practices within behavior-analytic research to identify strategies that can be used to obtain assent from potential participants with ASD and DDs. We began with a descriptive literature review of behavior-analytic articles that included the term "assent" to identify what practices behavior analysts have used to obtain assent from participants. In short, very few articles that clearly addressed assent procedures were identified. Thus, we propose a model for gaining assent when working with individuals with ASD and DDs.
